For an LTID system specified by the equation
a. Find the amplitude and the phase response.
b. Find the system response y[n] for the input x[n] = cos (0.5k - (π/3)).
Determine the smallest allowable physical distance between the centers of co-channel cells if N = 4 reuse is used, and each cell has a radius of 2 km.
How to create a eight-element row vector named vc that contains the elements of the second rows of A andthe fourth column of A?? and create a six-element row vector named vd that contains the elements of the first and fifth columns of a
Suppose that a public address system emits sound uniformly in all directions and that there are no reflections. The intensity at a location 26 m away from the sound source is 3.0 × 10-4 W/m2. What is the intensity at a spot that is 72 m away
The four alkaline battery cells store a total of 200watt-seconds of energy. If the cassette player is drawing a constant 10mA from the battery pack, how long will the cassette operate at normal power
a) Draw a sketch of the spectrum of x(t) = sin3(400πt) Label the frequencies and complex amplitudes of each component. Determine the minimum sampling rate that can be used to sample x(t) without aliasing for any its components.
A 20 MVA, 11 kV, 3-phase, delta-connected synchronous motor has a synchro nous impedance of 15 W/phase. Windage, friction and iron losses amount to 1200 kW.
A steel ring has a mean diameter of 20 cm, a cross-section of 25 cm2 and a radial air-gap of 0.8 mm cut across it. When excited by a current of 1 A through a coil of 1000 turns wound on the ring core, it produces an airgap flux of 1 m Wb.
The magnetic field produced in the air gap of an induction motor by the stator windings is given by B=Bm cos(wt-2theta) in which theta is angular displacement in the counterclockwise direction as illustrated.
1) For a semiconductor E vs kx near the band edge Ec is given by E=Ec +(h2/16m0)*kx2 Determine the effective mass of electrons in the conduction band. Here m0 is the mass of a free electron. 2) E vs. kx for electrons near the valence band edge Ev can..
